Abstract

The invention relates to an external lubricant for polyvinyl chloride (PVC) resin forming and processing and a production method thereof. The external lubricant for PVC resin forming and processing belongs to a polymer compound which is obtained by emulsion polymerizing a monomer with only one unsaturated ester group, and is characterized in that: styrene containing isooctyl glycolate, glycolic acid hexyl acetate, methyl methacrylate and butyl methacrylate are taken as polymerization monomers, potassium persulfate is taken as the initiating agent, sodium dodecyl benzene sulfonate is taken as the emulsifier, the conjugated polymer emulsion which is produced through a core-shell emulsion polymerization technology is adopted, so the external lubricant is produced after spray drying, the polymerization monomers have the weight percentages that: 10-45 of the styrene, 5-30 of the glycolic acid hexyl acetate, 15-45 of the methyl methacrylate and 5-25 of the butyl methacrylate. The invention provides the external lubricant for PVC resin forming and processing and the production method thereof, which can improve the lubricity, dispersibility and demoulding property, simultaneously have excellent processability, good plasticizing effect and high production efficiency.

Description

Technical field [0001] The invention is an external lubricant for PVC resin molding processing and a preparation method thereof. It is a polymer compound obtained by emulsion polymerization of monomers with only one unsaturated ester group. Background technique [0002] my country is a major producer and consumer of PVC resin. In recent years, with the rapid development of the national economy, the PVC industry has achieved great development. According to statistics, the production capacity of my country's PVC resin in 2009 has reached more than 12 million tons, the actual production volume reached 11.2 million tons, the apparent consumption volume was 10.5 million tons, and the annual growth rate reached 14.2%. With the development of the PVC industry, as my country's economy continues to prosper and maintain rapid growth, it has huge development potential. The country has promoted energy-saving emission reduction and circular economy development policies, economic and technol...
